Application filed May 13, 1895. Serial No. 549,148. (No model.)

To all whom, it may concern:

Be it known that I, WELCOME P. GAMMONS, J r., a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Machines for Uniting Sweat Leathers, Cloths, and Reeds, and Sewing the Same into Hats; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in sewing-machines, and more particularly to machines for sewing sweat-bands into hats; and it has for its main object to provide a in achine adapted to dress or cover the edge of a sweat-band or connect a sweat-band and reedcloth together by stitches placed comparatively close together, and connect the said sweat-band or sweat-band and reed-cloth to a hat by isolated stitches or stitches arranged a great distance apart, all in one continuous operation.

Other objects and advantages of the invention will be fully understood from the fol lowing description and claims when taken in conjunction with the annexed drawings, in which Figure 1 is a perspective View of the machine embodying my invention. Fig. 2 is an elevation of the side of the machine opposite to that shown in Fig. 1, with the hat holding or adjusting plate removed. Fig. 3 ma front elevation, on a scale larger than that of Figs.

1 and 2, of the machine with the hat-holding plate removed. Fig. 4 is an inverted plan view. Fig. 5 is a detail side elevation, with parts in section, of a portion of the mechanism through the medium of which the verticallyslidable frame carrying the stitch-forming mechanism is raised to permit of a ready interposition of the hatgbetween the needleplate ofisaid frame and the raised portion of the base of the machine. Figs. 6 and 7 are detail sections on the lines 1 l and 2 2, respectively, of Fig. 5. Fig. 8 is a detail front elevation with parts broken away illustrating a portion of the mechanism for feeding the materials forwardly. Fig. 9 is a section taken in line 3 3 of Fig. 8. Fig. 10 is a detail plan Fig. 11 is a detail vertical longitudinal section. Fig. 12 is a detail section taken on line 9 9 of Fig. 10. Figs. 13 and 14 are detail sections taken on lines 7 7 and 8 8 of Fig. 11, 5

respectively. Fig. 15 is a detail perspective view of the cam for raising the vertical rectilinearly-slidable frame. Fig. 16 is a detail section on the line 6 6 of Fig. 4. Fig. 17 is a detail section on line 5 5 of Fig. 4. Fig. 18 is a detail section on line 10 10 of Fig. 2. Fig. 19 is a detail section on line 11 11 of Fig. 2. Fig. 20 is a detail section taken on line 12 12 of Fig. 1. Fig. 21 is a detail section on line 13 13 of Fig. 20. Fig. 22 is a detail section In the said drawings, similar numerals des- 7 5 ignate corresponding parts in all of the views, referring to which I 1 indicates the base of the machine, which has the upwardly-extending or raised portion 2 at its forward end, upon which a hatbrim may be supported.

3 indicates the curvilinear plate for adj usting and holding a hat in proper position while it is being sewed, said plate being pivotally connected at its upper end to opposite sides of the base portion 2 and having its lower end adjustably connected to the base 1, preferably by a binding-screw 4, taking through a curved slot 5, so that the hat may be held at various angles of inclination while being sewed.

6 indicates the hollow, overhanging, and fixed arm, and 7 the main shaft which is journaled in said arm, as shown. This shaft 7 is provided above the hollow standard of 5 the arm 6 with a crank 8, which is connected to and serves to impart a rocking motion to an upright lever 9,(see Figs. 1 and 4,) for a purpose presently described. The said lever 9,

which takes through a slot 10 in base 1, has

its lower end connected to a slide-block 11, arranged in a groove 12 of a crank 13, at the rear end of a rotary shaft 14, to which said lever is designed to transmit motion. This Figs. 23, 24., 25, and 2c 70.

shaft ll is provided adjacent to its rear end with an eccentric 15, for a purpose presently described, and adjacent to its forward end and at its forward end said shaft is provided with cams 1G 17, as better shown in Figs. 4, 9, and 16 of the drawings.

18 indicates the toothed bar which is designed to extend through a slot 19 in the front of the base (see Fig. 9) and engage and feed the materials forwardly, and 20 indicates the plate of approximate obtuse-angle form to which the bar 18 is connected. This plate 20 is provided in its lower portion :21 with a slot 22, through which takes the bolt 23 for connecting said plate to the inclined portion 24 of the base 1, in such a manner as to permit the plate to move up and down and swing laterally, as presently described. At the lower end of its vertical portion the plate 20 is provided with a ball 25, to which is connected the upper end of the arm 26, through the medium of which motion is transmitted to the said plate and the feed-bar18 carried thereby. Said arm 26 is provided at its lower end with a socket 27, and in this socket is arranged. a ball 28, which is preferably formed integral with the arm 29, which is pivotally mounted upon a fixed rod 30 (see Fig. 4) and is provided in addition to the ball 28 with a frame 31, preferably of rectangular form, which receives and is engaged by the cam 17 at the forward end of the rotary shaft 11, whereby it will be seen that when said shaft is rotated and the lever 2.) is rocked, an up-and-down reeiprocatory movement will be transmitted to the plate 20, carrying the feed-bar l8, and as the lower portion 21 of the said plate bears against the inclined portion 24 of the base 1 the plate will be guided so that when it is moved up the feed-bar 18 will move forwardly through the slot 19 in the base, so as to engage the'materials, and when it is moved downwardly the feed bar 18 will recede through the slot 19, or move away from the materials, so as not to abrade or otherwise damage the same as it returns to the startingpoint of its forward stroke.

The arm 26, as better shown in Fig. 8 of the drawings, is provided at an intermediate point of its length with a slot 32. In this slot is loosely arranged a block 33, which is pivotally mounted adjacent to the forward end of areciprocatory bar 34, which has a depending portion arranged in the vertical slot of the head of rod 80, and also has lateral studs 36, arranged in the lateral slots of said head 35, and is loosely connected at its outer end to an arm 37, which in turn is loosely connected with the base 1. on the outside of the same, as better shown in Figs. 1, 3, and 8 of the drawings. Said bar 31 is further provided at an intermediate point of its length with a depending lug 38, (better shown in Fig. 8,) which takes into the longitudinal slot 39 of the lever 10, through the medium of which the bar 34 is reciprocated. This lever 40 is fulcrumed upon a pin 41, and it is pivotally or loosely connected at its rear end with a transverse slide 42, (see Figs. 4. and 16,) which has one of its ends extended through a guide-aperture 43 in the base 1, and may have its portion adjacent to said end reduced in width, as shown in Fig. 4, and also has its opposite end slotted to receive a guide and retaining-screw 44:, and is provided at an intermediate point in its length with depending branches 45 arranged on opposite sides of the cam 16 of the shaft it and designed to be engaged by the same.

The several parts thus far described are so arranged and timed that when the feed-bar 18 has been moved to its uppermost and outermost position through the medium of the lever 29, cam 17 on shaft 14, and arm 26, the cam 14; will move the slide 42 in the direction of the arrow (see Fig. 4) and will rock the lever 4.0, so as to move thebar 31 in the direction of the arrow in Fig. 8, and the arm 26 and the upper portion of the plate 20 and the feed-bar 18 in a corresponding direction, in order to enable said feed-bar to move the materials which are pressed against it, as presently described, forwardly. After the feed-bar 18 has reached the end of its forward stroke and has moved inwardly and through the opening 1.) and downwardly the cam 16 will move the slide at, lever 4.0, and bar 3& in the direction opposite to that indicated by arrow in Figs. 4 and. 8, and in consequence will return the feedbar 18 to the point where it commences its forward stroke.

It is desirable to have the throw of the feedbar 18 adjustable, so that the length of its throw and the spaces between the stitches formed by the stitch-forming mechanism presently described may be increased or diminished when desired, and to this end I arrange the square upper end of the fulcrum-pin l], which extends loosely through the slot 3!) of the lever 40, in a longitudinal guideway or groove 16, formed in the under side of the top of the base 1, and also arrange said pin -11 to receive a rod 48,to which it is fixed by a pin 47. This rod 4.8 is provided at its rear end with a binding-screw 40, which extends through a slot in the base 1 and is designed to bear upon said base and adj ustably fix the rod 48 against movement.

\Vhen the rod 48 and its fulcrum-pin 16 are moved forwardly or in the direction of the arrow, (see Fig. 4,) theportion of the lever 40 in front of the fulcrum-point will be shortened, and in consequence the stroke of the forward portion of the lever and of the plate 20, carrying the feed-bar 18, will be shortened, while when the fulcrum-pin -11 is moved rearwardly the portion of the lever 40 in front of the fulcrum-pin will be lengthened and the stroke of the forward portion of said lever and plate 20 proportionately increased.

Mounted in suitable ways in the face of the overhanging fixed arm 6 is the vertically-slidable frame 51, which is provided on its outer side with the forward]y-extending bracket 52. In this bracket 52 is journaled a rock-shaft 53, upon one end of which is fixed the swinging arm 54 of the rocking-or reciprocating needle (or needles) 55, while on the other end is fixed a crank-arm 56, for a purpose presently described.

Fixed at a suitable point on the main shaft 7 is a beveled gear-wheel 57, which meshes with a pinion 58 upon a short transverse shaft 59, which extends through the wall of the arm 6 and carries a disk 60 at its outer end, to which is eccentrically connected one'end of a pitman 61, which pitman is connected at its forward end to the crank-arm 56, whereby it will be seen that when the main shaft 7 is rotated the needle 55 will be reciprocated. The crank-arm 56 is provided at its upper end with a head 62, in which is formed a camslot 63-, designed to impart avertically-reciprocatory movement to a rack-bar 64, through the medium of the pin 65, carried by the said rack-bar 64, which rack-bar meshes with the V uppermost of three meshing pinions 66 67 68,

the lowermost pinion 68 of which is fixed upon one end of the shaft 69 of the loop-taker 70, which shaft is journaled in the frame 51. It will be seen that upon the inward stroke of the needle the rack-bar 64 is given an upward movement, which ban-through the medium of the several pinions 66, 67, and 68 gives the loop-taker shaft 69 a slight rocking motion, so as to vibrate the loop-taker and raise its point to a plane above the needle. Upon the downward stroke of the rack-bar 64, and during the receding stroke of the needle, the loop-taker will rock inwardly to take the thread from the needle, and upon the succeeding upper stroke of the rack-bar the loop-taker will rock outwardly or in a reverse direction into its position above the path of the needle, ready to rock inward to shed its first loop and take another loop from the needle, as will be hereinafter more clearly pointed out.

In order to enable the machine to sew a sweat band and reed cloth together by stitches placed close together and connect said sweat-band and reed-cloth to a hat by stitches at comparatively great distances apart in one continuous operation,l have provided,in conjunction with the vertically-slidableframe 51, certain mechanism for raising and lowering the same, which is illustrated in Figs. 1, 2, 3, 10, 11, 12, 13, 14, and-15 of the drawings, and will now be described.

71 indicates a frame, preferably of rectangular form, which is pivotally connected by pins 72 between short standards 73 risingfrom the upper end of the slidable frame 51, and is provided on the upper side of its lower bar 74 with a raised portion 75, and 7 6 indicates a rotary shaft which is j ourn aled adjacent to its rear end in a bearing 77 pivotally connected to a post 78 rising from the overhanging fixed arm 6, and is journaled adjacentto its forward end in a sleeve 79 which is arranged in avertically-movable upright 80,

frame, together with the frame 51.

presently described, and has its outer side rounded, asshown, so as to enable it to rock in the upright 80 for a purpose presently set forth. At its forward end the shaft 76 is provided with a cam 81, which has a flattened portion 82 and is designed to engage the frame 71 and raise the same and the frame 51, and in rear of said cam 81, and preferably formed integral therewith is a cam 83, which is preferbly of the shape shown and is designed when the shaft 76 is rotated to engage the portion 75 of the frame 71 and lower said The said cams or portions 81 83 of a single cam are so arranged with respect to each other (see Figs. 13 14) that when the cam 83 is in a position to lower the frames 71 and 51 the fiat side 82 of the cam 81 will be uppermost, so as not to interfere with the lowering of the frames, and when the rounded portion of the cam 81 is in engagement with the upper bar of the frame 71 the cam 83 will be out of engagement with the raised portion 75 of the lower bar of the frame 71, so as not to interfere with the upward movement of said frame and the frame 51.

At a suitable point in its length, preferably at a point immediately in advance of the bearing 7 7 the shaft 76 is provided with a ratchet or toothed Wheel 84, which may be fixed on the shaft in any suitable manner, and may have any number of teeth suitable to the purpose of my invention.- Said wheel 84, and

consequently the shaft 7 6, are held against retrograde or backward movement by the pawl 85, and said shaft is rotated from the shaft 14 through the medium of the eccentric 15 thereon, the bar 86, which has a strap 87, engaging the eccentric 15, the crank-shaft 87 which is journaled in the upright standard of the overhanging fixed arm and is provided at its inner end with the slotted arm 88, connected by a bolt 89 (see Fig. 24) with the bar 86, and at its outer end with an arm 90, the arm 91, pivotally mounted on the shaft 76 and carrying the detent 92, engaging the teeth of the wheel 84, and the pitman 93, connecting the arm90 and the arm 91, as shown. By this construction it will be seen that when the machine is in operation the wheel 84 and the shaft 76 will be turned the extent of a certain number of teeth every time the shafts 7 and 14 turn, and consequently the shaft 76 will be caused to rotate but once while the shafts 7 and 14 are rotating several times. By virtue of this it will be observed that the needle-arm 54, which gains its motion from the shaft 7, will rock or oscillate a number of times to make a number of stitches through a sweat-band and reed-cloth, while the frame 51 is in its uppermost position, and when the frame 51 is depressed or lowered by the action of the cam 83, and the fiat side of the cam 81 is uppermost, as shown in Fig. 13, the needle-arm will rock or oscillate once and will take asingle stitch through the sweat-band, reed-cloth, and hat so as to connect the connected sweatbandand reed-cloth to the hat, after which IIO the stitclrforming mechanism will be raised by the rounded portion of the cam 81 engaging the upper bar of the frame 71.

As will be readily observed by reference to Fig. 13, the curved portion of the cam 81 is much longer than the flattened portion 82 of the same. To this is due the fact that the frame 51 is held in its uppermost position sufliciently long to enable the stitch-forming mechanism to form several stitches through the sweat-band and reed-cloth, and is held in its lowermost posit-ion only long enough to enable said stitch-formin g mechanism to form a single stitch through the sweat-band, reedcloth and hat, it being readily observable that the first portion of the movement of the cam 81 from the position shown in Fig. 13 will carry the rounded portion of said cam into engagement with the upper bar of the frame 7 1 and will immediately raise said frame, the frame 51, and the stitch-forming mechanism carried thereby. The several parts just described are so timed that the frame 51 and the stitch-forming mechanism carried thereby will be depressed or lowered and also raised while the needle is out of or away from the materials.

The intervals between the depressions of the frame 51 and the stitch-forming mechanism, and consequently the intervals between the stitches which take through and connect the sweat-band, reed-cloth, and hat, may be readily lengthened or shortened when desired by connecting the bar 86 to the slotted arm 88 of the crank-shaft 87 at various distances from said shaft 87 it being simply necessary when it is desired to lengthen the interva s to connect the bar to the arm 88 at a greater distance from the shaft 87, so that each stroke of the pitman 98 will turn the wheel 81 the ex tent of but a few teeth, and the shafts 7 and 1a will be enabled to make a greater number of turns while the wheel 84: and shaft 7 0 are making but a single turn, and when it is desired to shorten the intervals it is but necessary to connect the bar 86 to the arm 88 at a point nearer to the shaft 87, so that each stroke of the pitman 93 will turn the wheel 81 the extent of a greater number of teeth and the shafts 7 and 14 will be enabled to make but a few turns while the wheel 8i and shaft 7 0 are making one.

95 (see Figs. 1, 2, and 25) indicates a block mounted and adapted to rock on the shaft 53.

indicates a longitudinally-slotted clamp ing-arm which is connected to the block by screws taking through its slot, and is adapted to slide on said block, as presently described.

97 indicates a bowed spring which is connected to the face of the frame 51 and bears at its outer end against a flange on the upper side of the block 95, so as to press the lower end of the arm 90 in toward the front of the base 1, and 98 indicates the presserfeet which is suitably connected in a pivoted manner to the lower end of the clamping-arm 90 and is designed to press the materials against the feed-bar 18. This presser-foot 98 is provided with a notch 99 for the passage of the needle, and with suitable guides 100 and 101 for the reception of a sweat-band and reed-cloth, and it is also provided with a lip or flange 102, (better illustrated in Figs. 1 and 2,) which is designed to rest above the hat-brim when the same is placed upon the raised portion 2 of the base 1 and hold the hat in position and prevent it from being raised by the feed-bar 18 during the upward and outward movement of the same before described.

At its upper end the clamping-arm 96 is pro vided with a suitable bearing 1.03, and in this hearing is arranged the lateral pin 10 1 at the forward end of the pitman 105, which pitman is slotted, as indicated by 106, to receive a guide-pin 107 on the side of the overhanging fixed arm 0, so as to enable it to serve also as a lever, and has its rear end connected to the arm 108 of the transverse crank-shaft 109. This shaft 109 is journaled in the overhanging arm 0, as better shown in Fig. 23, and it is provided at its end opposite to that which has the arm 108 with an arm 110, which is provided with an antifriction-roller, and is designed to be engaged and moved in opposite directions to move the clamping-arm 96 by the rotary cam 111. (Better illustrated in Figs. 1, 5, 23, and 27 of the drawings.) The said cam 111 is connected to the overhanging arm 6 by a screw 115, on which it is designed to turn, and it has a suitable handle 111 and is provided in its inner side with an approximately V-shaped recess 112, the wall 113 of which is designed to engage the antifrictionroller on the arm of the shaft 109 to move the presser-foot 98 away from the front of the base 1 and feed-bar 18, and is also provided with a shoe 116 at the lower side of the recess 112, which shoe is designed and adapted to engage the arm 110 when the cam is moved in the direction indicated by arrow a, see Fig. 5,) so as to move the lower end of the clamping-arm 90 and the presser-foot 98 toward the front of the base 1, so as to enable the spring 97 to perform its function of pressing the presser-foot against the materials.

The trunnion 118 on the inner side of the cam 111, which bears in a recess in the side of the arm 6 or in a suitable wear-plate connected to said arm, has a portion cut away, as indicated by 119, so as to allow play-space for the arm 110 of shaft 109.

It will be observed from the foregoing that then be rocked so as to move its lower end and the presser-foot 98 toward the base 1 and feed-bar 18 and enable the spring 97 to press the presser-foot against the materials, so as to clamp the same in position against said feedbar 18.

When the clamping-bar is raised and rocked to the position shown by dotted lines in Fig. 25, the connection between the pitman 105 and the arm 108, the guide 107, and the connection between the pitman 105 and the bar 96 will be brought into a line and a dead-center will be formed which will hold the bar 96 and presser-foot 98 in the position shown by dotted lines until the cam 111 is turned in the direction indicated by arrow a in Fig. 5. This is an important advantage, as it enables the operator to use both hands in placing the sweat-band and \the reed-cloth in the guides 100 and 101, respectively, of the presser-foot.

125 indicates a vertically-disposed wheel which is fixed on the forward end of the shaft 7, within the overhanging arm 6, and is provided in its forward side with a cam-groove 126.

127 indicates a vertical slide-block which is arranged on a fixed guide-rod 128 (see Fig. 18) and is provided with an antifriction-roller 129 or other device for engaging the cam-groove of the wheel 125. (See Fig. 11.)

130 indicates a vertical plunger-rod which is connected and adapted to move with the slide 127 and extends through and below the overhanging arm 6 and is provided adjacent toitslowerendwithanotch131. (SeeFig. 7.)

132 indicates a casting which has a vertical bore 133 to receive the rod 130, and also has a recess 134 to receive the spring-pressed latch 135, which is designed to normally engage the notch 131 of the rod 130 and fix the casting 132 with respect thereto.

indicates a needle-plate at the lower end of the frame 51.

136 (see Fig. 29) indicates a looper which has a finger 137 to engage the thread and is provided with an opening 138 of approximate obtuse-angle form to receive the guide pin 139, by which it isoonnected to the needleplate 115, and by reason of which and the opening 138 its lower end is moved inwardly toward the path of the needle when it is moved downwardly,'and is moved outwardly or away from the path of the needle when it is drawn upwardly, as will be hereinafter more fully described.

140 (see Fig. 3) indicates an arm which is pivotally connected at its outer end to an arm 141, fixedly connected to the frame 51, and at its inner end to the looper 136.

142 (seeFig. 1) indicates a lever which is fulcrumed at an intermediate point of its length on the side of the frame 51, and is loosely connected at its rear end to the casting 132 on the plunger-rod 130, and 143 indicates a link which connects the forward end of the lever 142 and the arm 140.

By reason of the construction just described it will be observed that as the shaft 7 and cam rotate, the plunger-rod and casting 132 will be reciprocated, the lever 142 and arm will be rocked, and the looper 1336 moved downwardly and inwardly toward the path of the needle and away from the path of the needle and upwardly, the first or down ward and inward movement being to enable the looper to take a loop from the thread, and the second or outward an d upward movement being designed to enable the looper to shed its loop, all as will be more fully hereinafter described.

It is necessary when it is desired to interpose a hat-brim between the needle-plate 115 at the lower end of the frame 51 and the raised portion 2 of the base 1 to raise the frame 51 and its needle-plate a considerable distance above the base portion 2, and in order that this may be done by hand at the same time that the clamping-bar 96 and the presserfoot 98 are moved away from the base and feed-bar 18, I provide the slidable plate 116, which is arranged on and suitably connected to an arm 117, connected to and extending laterally from the frame 51, and has its forward end backed by a spring 118 and its rear end beveled as shown, for a purpose presently described, and also provide the cam 111 with a shoulder 119 designed to engage the plate 116, whereby it will be seen that when said cam 111 is turned in the direction of the arrow in Fig. 1, and the cam-shoulder 119 engages the plate 116, the frame 51 and all of its appurtenances will be raised for-the purpose mentione h For the purpose of holding the shaft 76 (see Figs. 1, 6, 10, and 11) steady during the operation of the stitch-forming mechanism, and also to prevent casual raising of said shaft with the frame 51, I provide the depending portion of the verticzillyanovable bearing 80 with a notch 151, and also provide the horizontally-disposed springpressed latch 152,. which is connected with the overhanging fixed arm 6, and is designed to normally hold the bearing 80 and shaft 76 in the position shown in Fig. 11. It is necessary before the bearing 80, shaft 76, and frame 51 can be raised to permit of the interposition of a hatbrim between the latter and the raised portion 2 of the base 1 to disengage the latch 152 from the notch 151 in said bearing 80. To enable the operator to do this through the medium of the hand-lever 114 before the shoulder 119 of the cam 111 engages the plate 116 of the frame 51, I provide the said cam 111 with a shoulder 155, arranged in advance of the shoulder 119 and also provide the slide 156, (better shown in Fig. 1,) which slide is connected to the side of the overhanging arm 6, is adapted to engage the latch 152 and is provided with a device 157 (preferably an antifriction-roller) designed to be engaged by the cam-shoulder 155. Thus when the cam 111 is turned the shoulder 155 thereof will engage the slide 156 and through the medium of the same will disengage the latch 152 from the vertically-movable bearing 80 before the cam-shoulder 119 reaches the plate 116 on frame 51. It is also necessary before the bearing 80 and frame 51 is raised to disengage the latch 135 from the notch 131 of the rod 130, so as to enable the coiled spring 160, which is interposed between the lower side of the arm (3 and the casting 132, to move said casting 132 downwardly and thereby, through the medium of the mechanism described, raise the looper 136 above the lower edge of the needle-plate 115, so as to prevent said looper from catching into the hat and interfering with the interposition of the same between the needle-plate and the raised portion 2 of the base 1. To effect such disengagement of the catch 135 from the notch 131 of the rod 130, I provide the slide 165, which is connected to a plate 166, fixed on the side of the arm 6, and is adapted to engage the latch 135, and I also provide the cam 11]. with a shoulder 167 to engage the antifriction-roller 168 on the slide 165, as shown, whereby it will be seen that when the cam 111 is rotated the latch 135 will be disengaged from the rod 1130 simultaneously with the disengagement of the latch 15:? from the vertically-movable bearing 80.

\Vhen it is desired for convenience sake to -have the belt-pulley at the side instead of at the end of the machine, such pulley may be fixed on the auxiliary shaft 170, as shown by dotted lines in Fig. 22, and the shaft 7, which is connected by gearing with the shaft 170, as shown, rotated in that manner.

In the practical operation of the machine the holder 3 is adjusted to hold the crown of the hat to be sewed at the desired angle, and aft-er the clamping-bar 96 and the presser-foot 98 have been moved away from the front of the base 1 and the frame 51 has been raised through the medium of the handle 114:, as before described, the hat-crown is laid against the holder or plate and its brim is placed over the raised portion 2 of the base 1, after which the cam 111 is turned, through the medium of the handle 114-, sufficiently to enable the frame 51 to drop and clamp the hat-brim between its needle-bar 115 and the portion 2 of the base 1. Before the cam 111 is turned sufficiently to move the clamping-bar 96 and prcsser-foot 98 in toward the base and feedbar 18, the hat-sweat and reed-cloth are placed in position in the guides 100 and 101, respectively, of the presser-foot, after which the cam 111 is moved so as to move said clamping-bar and presser-foot and enable the sprin 97 to press and hold the presser-foot 9S and the sweat-band and reed-cloth carried thereby against the hat.

The machine is now ready for operation,and when the main shaft 7 is rotated it will be seen that the needle, properly threaded, will take a plurality of stitches through the sweatband and reed-cloth, and then when the frame 51 and its appurtenances are lowered or depressed, as described, will take a stitch through not only the sweat-band and reedcloth but also through the hat to connect the sweat-band and reed-cloth to said hat. After the single stitch through the sweat-band,reedcloth and hat, the frame 51 is raised in the manner before described and a plurality of stitches taken through the sweat-band and reed-cloth, after which the frame is again depressed and a stitch taken through the sweatband, reed-cloth and hat, and so on until the sweat-band and reed-cloth are connected together throughout their length and at intervals in their length to the hat. In this way, in one continuous operation with a single thread,the sweat-band and reed-cloth are connected together by stitches arranged close together and are connected to the hat by stitches arranged a comparatively great distance apart, which is highly desirable, inasmuch as stitches arranged close together, such as are the stitches which conn ect the sweat-band and reed-cloth, would tend to materially weaken the connection of the hat-brim to the crown.

W hen the connection of the sweatband an d reed-cloth together and to the hat is completed, the hat may be readily removed by raising the frame 51 in the manner described.

The movements of the needle-arm 51, looper 136, and loop-taker are preferably so timed that when the needles move inwardly the loop-taker will take two loops therefrom, and upon the succeeding outward stroke of the needles the looper will. engage the thread of one needle so as to form a bi ght, and will hold such bight in the path of the other needle so as to enable it to pass through the bight.
